Yes... the LED is lit in the car due to how the installer wired up the sled.

It appears if I can find an equivalent "Fuse and Filter" module to wire to the proper point on the sled, then splice to the yellow wire leading to my car, this will be fixed.

The question remains, what exactly is the "Fuse and Filter" module? Is it a simple in line fuse? Is it something I can pick up/order from a local Radio Shack?
